. GAS-HEATER.

Specification of Letters Patent. Pate ted i. 22 1921 Application filed. ma 18, 1920. Serial No. 382,333.

To an whom it may concern:

Be it known that I, EDWARD W. ZIMMER- MANN, a citizen of the United States, and

resident of the borough of Manhattan, city, county, and State of New York, have Invented certain new and useful Improve 'ments in Gas-Heaters, of which the following is a .description.

The present invention relates to improvements in gas heaters, particularly heaters adapted for use in connection with the ordinary illuminating gas jets, its primary object being to provide a heating device which may be conveniently attached to such jets ina manner as not to interfere with the illuminating effect thereof, and at the same time to produce maximum heating.

In particular I propose to so arrange the.

heating means in relation to the flame that the illuminating effect of the flame wlll not be dissipated, and also to provlde a heat absorbing element adapted to store and diate heat, and so constructed as to prevent the accumulation of soot.

I further propose to provide a screen or shield in connection with the heater for the purpose of dimming the light when desired, and at the same time maintaining a maximumheating eifect, and also, upon occasion, to cause reflection of the light and radiation of the heat in any desired direction into the room.

With these and other objects in view, an embodiment of my invention is shown in the accompanying drawings, and this em bodiment will be more fully described in relation thereto, and the invention will be finally pointed out in the claims.

In the accompanying drawings, Flgure 1 1s a perspectlve vlew, showing my improved heater connected to a gas jet.

Fig. 2 is-a bottom plan view of the heater. Fig. 3 is a vertical sectlonal view thereoi, and showing the screen or shield means connected thereto.

Fig. 4 is a detail view of one of the supporting brackets.

Fig. 5 is a plan view of the support ng plate, adapted to be connected to the 3et, and

Fig. 6 is an edge view thereof.

pered slightly as Similar reference characters designate corresponding parts throughout the several vlews of the drawings.

Referring to the drawings, the heater, ac-

cording to the present embodiment of my,

invention, comprises upper and lower plates 10 and 11, one nested within the other, and

of substantially pie pan shape, the beveled slde'walls 12 and 13. being inclined at different. angles, so that the plate 10 is of sub stantially greater depth than the plate 11. The lateral rim or flange 14 of the plate 10 is inclosed in the rim 15 of the plate 11, extending beneath and bent over the same to securely connect the two plates together. Thus a hollow pan shaped body is formed,

having a shallow concavity at its under side Within the concavity at the under side of the body there is provided a heat absorbing block or grate member 16 of elongated diamond shape, and secured to the fiat portion of the plate 11 by means of screws 17 and 18 at thecnds, the block member being preferably formed of cast iron or other suitable metal adapted to absorb and retain heat.

A series of transversely disposed slots 19 are formed in the block member 16 of decreasing length toward the ends, being ta 3. result of moving the cores in casting, and having the function of providing a relatively large under surface for contact with the flame and substantially largeand diverging passages through the block for the flow of heat therethrough. Theslots are in communication with perforations 20 in the plate 11, so that the heat flows into the space between the plates 10 and 11, and outwardly through other perforations 21 and 22, provided in the top and sides of the plate 11. i

The heater is mounted upon a plurality of supporting arms 23, curved to the form of the outline of a gas flame, and provided at their upper ends with outwardly and upwardly bent portions 2A, engaging perforations 25 in the rim of the heater, a substantially large number of these perforations bein provided toenable proper adjustment of tie heater to bring the heat-absorbing block 16 into proper relation with the flame.

The lower ends 26 of the supporting arms are bent vertically downward, and are screw-threaded, engag ng holes 27, provided I in a plate 28 having a central flanged opening 29 adapted to engage the gas jet 30, the supports being adjustably fixed upon the plate by nuts 31 and 32, provided above and below the plate, and permitting raising or lowering of the heater relatively to the jet. he upright portions of the ends 24 of the supports enable the heater to be readily lifted therefrom, and to this purpose an inverted U-shaped handle 33, having inwardly bent ends 34 and 35, is engaged in holes 36 and 37 in the plate 10, and may be engaged, upon lifting the same, by a suitable hook or the like,"as indicated in Fig. 3, to raise the heater from the support when it is no longer desired to heat the same, so that it may be allowed to cool without turning out or lower ing the light. Inasmuch as the heater, according to my invention, is adapted to absorb and radiate heat for a relatively long period, it will be possible to carry the same into other rooms which may not be provided with gas jets, and heat the same in this manner. v The handle will prove of use in such case, to enable the heater to .be suspended upon a hook provided in such rooms.

In use the heater is disposed in such relation to the flame that the full flame is ex posed beneath the heater, and is not deflected, or spread, as has heretofore been the case in such heaters, so that its lighting efl'ect is not impaired. The heat-absorbing block is arranged to follow the line of the flame, so that it receives the full heating efi'ect therefrom, the flow of heat being upwardly through the slots of the block member, and into the space between the plates 10 and 11, where it mushrooms and is forced outwardly through the perforations 20 and 21, and into the room, the relatively large surface. area of the plates, at the same time absorbing and radiating the heat into the room. The construction results in a positive flow of heat into the room as distinguished from such heaters heretofore in use, in which there has only been a rising radiant heat. The slots in the block member will prevent the accumulation of soot and the production of smoke.

In order to shield the light when desired, and deflect the heat to particular parts 01" the room, I provide a plurality of shields 38 formed of mica, metal or other suitable material, being rectangular in shape, and secured at their upper edges in U-shaped binding strips 39 following the curvature of the periphery of the heater, and being provided with a sheet metal hook 4:0,adapted to be engaged with one of several elongated slots 41, provided in the lateral rim of the heater,

so that the shield will hang downwardly about the flame. The mica or other material is preferably opaque, Or very dark, so that it will shield the light, this being especially desirable when the heater is used in a sick room. The shields are preferably of such size and number as may extend entirely about the light, and overlap, as at 42. (Fig. 3.)

I have illustrated and described a preferred and satisfactory embodiment of my invention, but it is obvious that changes may be made therein, within the spirit and scope thereof, as defined in the appended claims.

I claim:

1. A gas heater of the character described, comprising a hollow body, having a recess at its under side, a heat-absorbing lock secured within said recess, and provided with openings extending therethrough, said body having openings in communication therewith.

2. In a gas heater of the character described, comprising a hollow body consisting of upper and lower spaced plates, a heat-absorbing block secured to one of said plates, provided with openings extending therethrough, said body having openings in communication therewith, and adapted to conduct heat into said hollow body.

3. A gas heater of the character described, comprising a hollow body, consisting of upper and lower spaced plates of pan shape, one of said plates being of greater depth than the other, said plates being connected at their peripheries to form a space therebetween, and a heat absorbing block secured within the recess of the plate of smaller depth.

a. An improved gas heater comprising a block adapted to be secured above a gas-jet and composed of a body elongated in the direction of the width of the gas flame, and being of substantially narrow width, said block being enlarged laterally at its central portion, said block also having openings therethrough, and a chamber in connnunication with the openings in the block and having outlets to the atmosphere.

5. A gas heater of the character described comprising a heater body, supporting means for holding the heater body at an elevation above a gas-jet, means whereby the supporting means may be adjusted as to height, the upper portion of the supporting means freely receiving the heater body and adapted to permit lifting of the heater body therefrom, and a handle on the heater body providing for its support when lifted in a heated condition from the supporting means and adapted to permit the heater body to be suspended without the use of said supporting means.

6. An improved gas heater of the character described comprising a heater body, means for supporting said heater body at an elevation above a gas-jet, and a shield extending downwardly from the side of the heater body, and cooperating means between said shield and the heater body to permit removal of the shield from the body and its adjustment about the same.

7. A gas heater of the kind described comprising a body having openingsto the atmosphere, and a block secured to said body and having openings in communication with the interior of the body, and means to support the block above a gas-j et.

In testimony that I claim the foregoing as my invention, I have signed my name hereunder.
